Hello -- I am working with an Aeolian player piano built about 1980
and the player mechanism seems to be leaking vacuum.  The electric pump
pumps up to 35 inches of water vacuum, and the reservoir does entirely
collapse when turning the vacuum pump back on.

I believe the problem is with the valves leaking, and that I should
replace them.  I'd like to know if anyone else has had this problem.

Thanks in advance,
Victor Wolfe
